National Summary


Mainly dry today. Some sunny spells will develop, best in western and southern areas, but cloud will tend to persist in some places, especially in northern and eastern areas. Fresher than of late, with top temperatures 7 to 9 C., in light to moderate south to southeast winds.


Tonight will be cold, but mainly dry, with clear spells. Temperatures falling close to freezing in many places, allowing frost and some mist to develop. But temperatures will be a little higher over much of Ulster and north Leinster, where cloud is likely to persist.


Tomorrow, Friday, will be a dry, bright day, with light to moderate southeast winds. Sunny spells developing in many areas after a frosty start and temperatures of 7 or 8 C.


On Friday night temperatures will fall to just below freezing and a frost will develop in places. It'll be a largely dry night once again with light southeast winds and clear spells. Saturday and Sunday will both be mainly dry days with some sunshine, but a little patchy light rain or drizzle is likely in coastal areas at times. Daytime temperatures will range between 3 and 6 degrees on both days and winds remain light southeasterly through Saturday, becoming variable in direction by Sunday. Frost will develop on both nights as temperatures fall to as low as minus 4 degrees in places, and are likely to be below freezing both nights in most areas. Current indications suggest that it will become windy by midweek, with temperatures on the rise again from midway through Monday. While the overall picture remains largely dry, there's the suggestion of some rain on the northwest coast later on Tuesday.
